At Barnsole Primary School, we believe that all of our children should leave primary education as confident, resilient mathematicians with a deep conceptual understanding of the skills required to approach any maths problem. As such, we follow a mastery approach, embedding the principles of concrete, pictorial and abstract in all lessons where appropriate within a clear teaching sequence. We promote the use of mistakes and misconceptions as part of the learning journey and provide challenge to all abilities through targeted and open ended questioning.



At Barnsole, we follow the White Rose Maths planning scheme from Year 1 upwards. Whilst the scheme suggests a chronology, teachers are also guided by the needs of their cohort to ensure any gaps in understanding are addressed. All adults model and encourage the use and application of correct vocabulary, building on prior knowledge and experience. We aim for all pupils to:

  • become fluent in the fundamentals of mathematics and develop conceptual understanding along with an ability to recall and apply knowledge rapidly and accurately.
  • be able to solve problems by applying their mathematics to a variety of problems with increasing sophistication, including in unfamiliar contexts and to apply them across the wider curriculum.
  • reason mathematically and present a justification, argument or proof using common mathematical language.

In EYFS, children are taught fundamental skills such as accurate counting, number recognition, subitising, and shape through rhymes and play based activities.


It is imperative that the children have a secure understanding of each mathematical concept. Teachers and support staff deliver targeted maths interventions and boosters based on assessment of the work produced to ensure that all children are ready to move on. Children are tested on the content they have been taught after each term and the gap analysis data informs future planning and interventions.


At Barnsole, we take every opportunity to exploit mathematical learning across our curriculum offer. We practise and embed mathematical learning through Science, Geography, PE and History lessons are also closely planned with maths in mind to ensure children have the opportunity to explore maths through our alternative and creative approach to topics. All children are exposed to open-ended investigations, which are presented through a real life context. In their approach to these tasks, the children learn the invaluable skills of collaborative planning and systematic working. We ensure that mathematics has a particular relevance for our pupils, and is not just a subject that is taught at school.
